BUB1(also called Mitotic checkpoint serine/threonine-protein kinase BUB1and BUB1A) is a kinase involved in spindle checkpoint function. The kinase functions in part by phosphorylating BUB3, a member of the miotic checkpoint complex, and activating the spindle checkpoint. Mutations in this gene have been associated with aneuploidy and several forms of cancer. BUB1 is autophosphorylated when cells enter mitosis. This protein is localized to the nucleus in interphase cells. Kinetochore localization is required for normal mitotic timing and checkpoint response to spindle damage. BUB1 is highly expressed in testis and thymus, less in colon, spleen, lung and small intestine. Expression is associated with cells/tissues with a high mitotic index.
